Quick Answer

A lash tray label should tell you the curl, thickness, length range, finish, fiber type, SKU and batch code. These details help salons match the tray to the service menu, approve samples, reorder the same product and avoid mixing similar-looking trays.

A useful tray label should make curl, thickness, length, finish and batch information easy to confirm.

When reading lash extension trays, do not only look at the product name. Check the label fields that affect the final set: curl shape, lash diameter, row length, finish, material description and batch reference.

Lash Tray Label Fields

Label field Example What it tells you
Curl C, CC, D, J, B, LC, L, M The lift and shape of the set
Thickness 0.03, 0.05, 0.07, 0.10, 0.12, 0.15mm Whether the tray fits classic, volume or mega volume use
Length 8-15mm mix or 10mm single The row map or exact length
Finish Matte, soft black, brown, cashmere The visual texture and color effect
Fiber / style Classic, volume, easy fan, premade The intended application method
SKU Internal reorder code Helps repeat the approved item
Batch code Production or approval reference Helps compare sample and bulk order

Why Lash Tray Labels Matter

Many lash trays look similar at first glance. Two trays can both be black, soft and full, but one may be 0.05mm volume and another may be 0.15mm classic. A clear label prevents the artist from choosing the wrong tray during a service.

For wholesale lash buyers, label clarity also protects reorder accuracy. If the approved sample says `C Curl / 0.07mm / 8-15mm Mix`, the reorder should match that exact spec unless the buyer intentionally changes the product.

Curl, Thickness and Length

These three fields are the core of the tray label.

Field Buying question Example use
Curl Does this match the service menu? C for everyday lift, CC or D for stronger lift
Thickness Is it classic or volume? 0.10-0.15mm for classic, 0.03-0.07mm for volume
Length Is it single or mixed? 8-15mm mix for mapping, 11mm single for refill stock

If the tray is mixed length, the row map should be easy to read. If the tray is single length, the length should be clear enough for fast salon storage.

Finish, Fiber and Style Names

Finish names help describe the visual effect, but they should not replace the actual technical specs. A tray labeled soft matte still needs curl, thickness and length information. A cashmere-style tray still needs diameter and length details.

For buying and reorder planning, treat style names as support information. The technical label is what keeps the bulk order repeatable.

SKU and Batch Code

The SKU is the reorder shortcut. The batch code is the reference point for sample approval and bulk matching. If a salon approves a sample, record both.

Record Why to keep it
SKU Makes reorder faster
Batch code Helps compare sample and bulk production
Approval date Shows when the tray was accepted
Artist notes Captures pickup, strip release and curl feedback
Packaging note Helps private label buyers avoid label confusion

How To Check A Lash Tray Before Ordering

Use the label as the first check, then test the tray physically.

  1. Confirm the product type.
  2. Match curl to the service menu.
  3. Match thickness to classic or volume use.
  4. Check length rows or single length labels.
  5. Review finish and color wording.
  6. Record SKU and batch code.
  7. Test pickup, strip release and curl consistency.

FAQ

What information should be on a lash tray label?

A lash tray label should show curl, thickness, length, finish, product type, SKU and batch code so salons can match services and reorder accurately.

Why is thickness important on lash extension trays?

Thickness tells the artist whether the tray is suited for classic, volume, mega volume or soft volume work. It also affects density and natural lash load.

What does 8-15mm mix mean on a lash tray?

An 8-15mm mix means the tray includes multiple lengths from 8mm through 15mm. It is useful for lash maps and flexible salon stocking.

Why should salons record batch codes?

Batch codes help compare approved samples with bulk orders and make it easier to investigate any change in curl, pickup, finish or label accuracy.

Is a style name enough for reorder planning?

No. Style names such as matte, cashmere or soft black are useful, but reorder planning should still record curl, thickness, length, SKU and batch code.
